About the only place this will work (economically) is for satellites in geosynchronous orbit (about 26,000 miles up, the satellite appears to hover over a specific location.) In this orbit you can move from one satellite to the next with small amounts of fuel (they are all moving at the same speed and more importantly in the same direction.) Satellites in any/all other orbits are travelling at enormous velocities in thousands of different directions. The fuel required to change orbits to move from one satellite to the next would be huge.
